“When Tim and I came home for the first time to get him clothes to be buried in, this is the note we found from him on the table in the living room. We have no idea when he wrote it but you can tell he was always a special child. We will love you forever Leland. Sleep tight and don’t let the bed bugs bite!”

Leland had been in critical condition at Children’s Healthcare of Atlanta. It remains unclear how the boy contracted the infection, according to WSB-TV.

His parents created a GoFundMe page to raise money for hospital bills.
